Chronic lymphocytic leukemia (CLL) immunoglobulin repertoire is biased and characterized by the existence of subsets of cases with closely homologous ("stereotyped") complementarity-determining region 3 (CDR3) sequences. In the present series, 201/916 CLL patients (21.9%) expressed IGHV genes which belonged to one of 48 different subsets of sequences with stereotyped heavy chain (H) CDR3. Twenty-six subsets comprised 3 sequences and were considered "confirmed". The remaining subsets comprised pairs of sequences and were considered "potential"; public-database CLL sequences were found to be members of 9/22 "potential" subsets, thereby allowing to consider them also "confirmed". The chance of belonging to a subset exceeded 35% for unmutated and/or selected IGHV genes (e.g, IGHV1-69/3-21/4-39). Comparison to non-CLL public-database sequences showed that HCDR3 restriction is "CLL-related". CLL cases with selected stereotyped IGs were also found to share unique biological and clinical features. In particular, cases expressing stereotyped IGHV4-39/IGKV1-39-1D-39 and IGHV4-34/IGKV2-30 were always IgG-switched. In addition, IGHV4-34/IGKV2-30 patients were younger and followed a strikingly indolent disease, contrasting other patients (e.g., those expressing IGHV3-21/IGLV3-21) who experienced an aggressive disease, regardless of IGHV mutations. These findings suggest that a particular antigen binding site can be critical in determining the clinical features and outcome for at least some CLL patients.
